F. H. CULLEN SMOKE PURIFIER Filed Feb. 23, 1942 INVENTOR. @wen/ Patented Jan. `9, 1945 SMOKE PURIFIER i A Francis H. Cullen, Philadelphia, Pau` i i pplication February 23, 194.2,` Serial No`.fl31,939` 21 claims. (011131-173) My invention relates to new and useful improvements in a smoke purifier for tobacco smoking appliances,` for purifyingthe smoke entering into the mouth of the smoker.

" The purpose` of the invention is toprovide improved means for absorbing the oils and, other objectionable substances from the smoke i fumes and in `addition to pass the fumesthrough a liquid bath to further condense, cool, sweeten and purify them so as to prevent-.tongue burning and biting'r and give the smoker a pure, cool, sweet Smoke. Y y i ,The general object ofthe invention isto provide a novelconstruction` of asmoking appliance, which provides a `danger signal, tojwarn the smoker that the condensation and saliva formed inthe Smoking app1iancedueto smoking, must not be exceeded, otherwise, the smoker will draw someof Jthe condensation into his` mouth. 'I'his danger `Signal may also be used to warn the Smoker that any liquidhe may first employ in ,the smoking appliance, plus the condensation due to smoking, mustnot be exceeded, otherwise, the smokerwill draw some ofthe combined liquid and condensation into his mouth.

"Another'object of the invention is 'to provide a dangersignal that may be used to register a portionof the condensation and salivaformed within the smoking appliance, due to smoking, to warn the smokerthat this danger point must notbe exceeded, otherwise, the smoker will `draw intolhis mouth somefof the. condensation and saliva. The said danger signal may also be used to` register a `portion of the liquid that iS'rSt employed` in the appliance plus the condensation that may form due to smoking.`

Another object of the invention is to provide a measuring means so that the smokermay know that he has placed enough `1iquid,'where first employedi'n the appliance, to form al liquid seal. Another object of theinventionis to provide a removable tubular member within the discharge chamber of a `smoking appliance, said tubular member containing a partition, the forward end ofthe member or endnearest the tocylinder, either or both of which may 16@I made ofeither an inexpensive or absorbent material and after they have served theirpurpose may be r discarded and thrown` away.

A still furtherobject of theinvention is to pro-V vide a 'tubular member that is removable and whichmay4 ber made, vfor instance, from specially treated papen'such `as parchment paper and `said member may have an outer jacket of parchment paper andan innerlayer `of absorbent material `or any other suitable .filtering substance.

With the above andL other objects in view, this invention consists of the details of construction and combination of `elements hereinafter set forth and then ,designated bythe claims.

In order `that those skilled in the artto which this invention appertains may understand how to make and use the Same, I will describein detail certain means `forcarrying` `out the objects of this invention, referring by numerals tothe accompanying drawing forming a part hereof, in which: i

Another` object of theinvention is to provide a tubular member with a condensing cylindensaid .cylinder being a part of or detachably connected tosaid tubular member. 1

terior of the tubular member 29, forward of the partition 30, and the condensing chamber 34.

In order to properly position the condensing cylinder 3| on the tubular member 29 and prevent the cylinder from sliding backward, said tubular member may have a flange, rib or other suitable formation 38 to engage the outer surface of the end Wall 32 and hold the condensing cylinder in place against the ledge I4.

vThe tubular member 299 "is supported by the induction and eduction tubes andin turn said tubular member supports the condensing cylinder -incooperative relation to the ledge I4.

The outlet orifice 35 from the condensing chamber is to be sealed by a liquid 39 contained .finithe Adischarge chamber I3 and this liquid will On the adjacent or inner -endssofboth' .thefinf duction and eduction tubes are placed the ends of the tubular member f2.9 .or anequiVal'ent member such as shown at l.29a land2l9b. .Thev tubular [meme ber 291isopen at both ends so as .tol.communicate with the induction andeduction ,tubesandhas 1a partition or barrier `3l) intermediate .its ends".

`From the foregoing itwill be obvious that the smoking appliance canbe placed in various positions without the likelihood of the liquid reaching the interiors of the induction and eduction tubes through their respective port openingsandientering `the tobacco `chamber or the smokers mouth. This is due to the positions of the lateral port openings in the tubular member 29.relative to the surrounding walls and to the fact that said lateral port openings are at right angles to the general direction of flow of the liquid when the smoking appliance is upended in either direction.

During the smoking of` the pipe, the path of travel of the draft is from` thetobacco bowl then through the induction tube 23, the forward or induction end of the tubular member 29, the lateral port openings 3l,` the condensingcharnber i 34, outletorice 35, the liquid seal 39 in the dis- `charge chamber, said-discharge chamber, the lateral port openings 36, the rear or eduction end of the` tubular member, the eduction tube 26, and

the opening 2l in the bit 2|] to the smokers Aof said tubular member 29 from either the induction tube l23 or the eduction tube 26 or both.
